    CNT DOWNPIPE?! stage 2 questions

    Hey guys i'm getting the cobb accessport for christmas and i already have a cat back exhaust. i want to get a downpipe for cheap that is CATTED. i'm too scared to go catless and dont try to persuade me to do it. iv'e made my decision. So far i found that the CNT downpipe is very reasonable, its like $370 for a catted. Is there anyone that can recommend or give reviews on this downpipe. How does it compare with other bigger name brands like invidia and cobb? thanks guys

    Well my main concern would be the quality of the catalytic converter used. Those eBay companies have to save money somewhere. If you were Catless then I'd say your all good. My buddy bought a full catless turbo back for his bugeye off eBay for like $300 and its still running strong. No rust, no problems fit perfect. And that was 3 years ago.

    Just my recommendation, if your dead set on having a cat.(and you should be, there's no reason to go Catless under about 400whp) Then save up the extra $200 and buy a good brand down pipe. I.E. Cobb, Perrin, etc....

    I have not been happy with the CNT/ERZ pipes I've installed; every one has had crappy fitment. Other people haven't had issues. Personally, I'd go with either a Perrin, Invidia, or Cobb unit.

    Incorrect. When boost creep isn't an issue, catless will offer more power and better response than a comparable catted version.

    The cat in the CNT is fine but EJ257 is right fitment isn't the best. Installing a dp on this car should be easy but installing mine took over two hours and a lot of swearing! Now that it's in though everything has been fine. Been pretty cold here in vt and not even a little bit of boost creep. I bought mine used though for 200 bucks so I couldn't pass that up.

    I stand corrected!!!! Just going off what Perrin(over the phone) told me when I asked them the power difference between their catted and catless stage 2 maps. I was told the difference is negligible. Something like ~5hp. They said under about 350-400 whp there isn't much power gained going full catless. But like I said this is just an over the phone information if you have real world knowledge and numbers then I do stand corrected sir!!

    I don't believe they sell a catless downpipe for stock-location setups. Also, with their rotated setups, they only sell kits where the EWG is routed into the downpipe.
